摘要
作者对２０只尸体手进行了解剖研究，结果证实拇短屈肌与拇短展肌的起点有约１／２相互重叠，两个肌腹近端有约１／３相互重叠，拇短屈肌主要止于近节指骨基底掌侧，拇短展肌止点以掌指关节桡侧为主。拇短屈肌受尺神经深支支配率为１００％。将拇短屈肌的止点向桡侧移位，使两肌纵轴作用力的夹角增加７°～９°，有利于拇短屈肌的对掌功能。临床应用８例，术后平均随访１２个月，功能均为优。这种新的手术方法具有创伤小，不用另取肌腱移植，效果可靠等优点。
AbstractAnatomical study was performed on 20 cadaverichands and the results showed that M. flexor pollicisbrevis overlap the M. abductor pollicis brevis for abouthalf of its width at their origins and the overlappingreduced to about 1/3 of the width at the muscle bellylevel.The M,flexor pollicis brevis chiefly inserts onthe palmar aspect of the base of proximal phalange.The M. abductor pollicis brevis primarily inserts to theradial side of MP joints, the M, flexor pollici;brevis isentirely innervated by the deep branch of the ulnarnerve. In ordex to increase the angle bettween longi-tudinal force lines of these two muscles for 7～9°,theauthors transfered the insertion of the M. flexor ptilli-cis brevis to the radial side of the lnetacarpal-pha-langeal joint,so that it gives this muscle the functionof opposition. Eight patients had been treated dnd fol-lowed up on average for 12 months. All had fine func-tional results. This new methodis effective,least trau-matizing and does not need transposition of anothertendon.
